🍁Alternanthera Aquarium Plant: Red Eye-catcher in the Aquarium🍁

Alternanthera is a striking aquarium plant loved for its bright red to deep purple leaves. This plant is a real eye-catcher and is often used as a color accent in aquascapes. With the right lighting and nutrients, its color will truly shine.

🌱 What is Alternanthera?

Alternanthera is a genus of plants that occurs in both emersed and submerged forms. The aquarium species, especially Alternanthera reineckii and its variants, are known for their red leaves and compact growth. They have slightly higher requirements than many green plants, but they reward you with unique splashes of color.

🌺 Popular Alternanthera Species

Alternanthera reineckii 'Rosaefolia '	Red/pink	20–50 cm	Average

💧 Care & Growth

Light: Highly recommended (intensive light for color retention)
Temperature: 22–28°C
pH: 6.0–7.5
CO₂: Highly recommended for compact and colorful growth
Nutrition: Iron-rich liquid fertilizer is crucial

Alternanthera grows slowly to moderately. Without sufficient light and CO₂, the red color fades and the plant can wither.

✂️ Pruning & Propagation

To keep the plant bushy, regularly prune the top above a leaf node. Replant the cutting in the ground for a dense clump.

Prune every 2–3 weeks to maintain shape and color
Leave the lower leaves intact for photosynthesis
New shoots often grow from the side nodes

🎨 Aquascaping Applications

Alternanthera is the perfect plant for a bold splash of color in a layout. Use it as an eye-catcher in Dutch-style tanks or as a contrasting plant among green varieties in nature-style aquascapes.

Mini varieties: Foreground or mid-planter
Large Species: Background or Central Focus
Combine with: Green plants such as Rotala green or Limnophila sessiliflora
